AS 4773.2:2010 PDF Download

AS 4773.2:2010 is a standard that provides guidelines for the construction of masonry in small buildings. It specifically applies to buildings of Class 1 and Class 10a as defined in the BCA (Building Code of Australia) and designed in accordance with AS 4773.1. The standard covers masonry units made from clay, concrete, or calcium silicate that comply with the requirements stated in Section 2.

Some key provisions in the standard include that the thickness of masonry should be 90 mm or greater, walls should be laterally supported by a roof or floor structure (except for specific exceptions like parapets, chimneys, and cantilevers), and walls should be supported on concrete slabs or footings in compliance with AS 2870 or suspended slabs in compliance with AS 3600.

The standard does not cover topics such as acoustics and energy efficiency, construction of attachments like satellite dishes, masonry made from autoclaved aerated concrete units, and structures designed for earthquake actions. The scope of the standard advises referring to the BCA for acoustic and energy efficiency requirements and using AS 3700 for applications outside its scope.

Additional information on the construction process, including drawing and specification requirements, can be found in Appendix A, while guidance on cleaning masonry is provided in Appendix B.
